FIELD OF THE INVENTION

This invention relates to hair styling devices and, more particularly to a vibrating hair-styling device with a non contact switch for straightening human hair.

DISCUSSION OF RELATED ART

Presently, a wide variety of hair-styling devices has been developed in the art for improving the appearance of human hair. The hair-styling devices are used for providing a variety of styling effects to the hair. Among the hair-styling devices, hair irons play a vital role in smoothing, streamlining and providing a ‘sleek’ appearance to the hair. In most hair irons, heating and vibrating mechanisms are used for straightening human hair.

One prior art taught in U.S. Pat. Application No. 20090044823 published to Overend discloses an electric hair iron comprised of at least one heating element controlled by a temperature sensor and a control circuit. The temperature sensor and control circuit are configured so that power is supplied to the heating element or elements only when the temperature reaches or exceeds a predetermined minimum temperature. Also provided are methods for straightening hair. However, the temperature sensor activates only after a predetermined minimum temperature, causing the hair iron to take a long time to heat and straighten the hair.

U.S. Pat. No. 6,386,206 issued to Lee discloses a hair iron that includes a pair of arms opened and closed by a pivot, and each arm has a gripping portion and a hair treatment portion. The hair treatment portions are provided with respective hair treatment members between which the desired amount of hair is held and pressed to style the hair. The hair treatment members are comprised of planar top surfaces, or undulating top surfaces. An image marker of concave and convex images are provided on the opposing surfaces of the hair treatment members, which are also supported by supporting protrusions formed on the arms. When the arms are closed, the hair is held between the hair treatment members and part of the hair is also held between the image marker so that an image is imparted with the part of the hair by the pressure and temperature applied to the hair. However, for creating a desired hairstyle, a user wants to pull down the hair iron by pressing the arms after holding the hair between the forming plates. This may cause damage to hair and therefore the device is often ineffective for straightening the human hair without harming the hair.

Another prior art discussed in U.S. Pat. No. 5,223,694 issued to Tsuji provides a hair styling iron for hair straightening or curling, the device includes a generally circular cross-section electrically heated barrel. An arm is movable relative to the barrel for selectively clamping a strand of hair between the tongue and the peripheral surface of the barrel for curling hair. The barrel comprises first and second pipes each having a generally semi-circular cross section with a top rounded outer surface and a flat bottom outer surface. The pipes are movable relative to each other between a closed position where the flat bottom surfaces are kept in closed relation to each other and an open position where the bottom surfaces are spaced away from each other. However, the device is not secure because of the electrical power from the contact switch may cause for occurring defects on human body while straightening the human hair.

Therefore, there is a need for a hair iron for straightening the human hair with a vibrating mechanism. Such a needed device would have a noncontact on/off switch for controlling the vibrator. The noncontact on/off switch would be more durable than a mechanical switch and would last for a longer period of time. The noncontact switch would be capable of reducing the chance of occurring defects on human body when the vibrating hair-iron is in use. The needed device would be easy-to-use, reliable with the capability to straighten human hair with a smooth, silky, and luscious shine. Such a needed device would have a shorter heat-up time and a user would be able to straighten hair within minutes. Finally, the needed device would have high quality, ceramic tourmaline plates to prevent hair from drying out from use.

SUMMARY OF THE INVENTION

The present invention is a vibrating hair-styling device with a noncontact switch for straightening human hair. The vibrating hair-styling device comprises a pair of arms pivotally arranged as an upper arm and a lower arm, an upper heating plate, a lower heating plate, a magnet, a non-contact switch, a power on/off switch, a vibrating motor, a control circuit, a power cord and a Light Emitting Display (LED). The upper heating plate is attached at a distal end of an inner surface of the upper arm. The lower heating plate is attached at a distal end of an inner surface of the lower arm. The noncontact switch is arranged in magnetic communication with the magnet and the noncontact switch being at a slot on the inner surface of the lower arm. The power on/off switch is arranged at a middle portion of the inner surface of the lower arm. A vibrating motor is operatively arranged inside a middle portion of the upper arm. The power cord is connected to the control circuit through a joining end of the upper arm and the lower arm.

The noncontact switch may be a magnetic sensor which does not require a physical contact and thereby reduces chance for occurring defects on human body. The noncontact switch has a hysteresis that allows the stable operations without the chattering malfunctions. The upper heating plate and the lower heating plate adopt a floating style to make the vibration easier and to vibrate in three different axial directions.

The power on/off switch turns on when the magnet and the noncontact switch approach each other in the closed position and transfer vibrations to the upper heating plate and the lower heating plate. The user can place the hair in between the upper heating plate and the lower heating plate and slide the device over the hair for straightening and smoothing the hair. The user can repeat the process until he/she is satisfied with straightness and smoothness of hair. Further, the present invention is having a fast heat up time and the user can straighten the hair within minutes. Finally, the device is having a high quality ceramic tourmaline plates for retaining the moisture in the hair. Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.
